Canthoplasty, commonly known as “cat eye surgery,” is a cosmetic or reconstructive surgical procedure designed to alter the shape and position of the outer corner of the eye, also known as the canthus. The procedure is often performed to achieve a more youthful or almond-shaped eye appearance. In some cases, it is done to restore function and improve vision by correcting eyelid malpositions like sagging. Whether for cosmetic enhancement or medical necessity, canthoplasty is becoming increasingly popular due to its transformative results. This article will explore what canthoplasty is, the types, benefits, risks, and the recovery process.

Canthoplasty is a delicate eye surgery that reshapes the lateral canthus, the corner where the upper and lower eyelids meet on the outer side of the eye. The aim is to tighten and lift the lower eyelid, reposition the canthus, and reshape the eye for either aesthetic or functional reasons. The procedure can give the eyes a more elongated, youthful look and is frequently combined with blepharoplasty (eyelid surgery) to achieve comprehensive results.

• Lateral Canthoplasty: This is the most common form of the procedure, focusing on adjusting the outer corner of the eye to improve its shape and position. It is often used in cases of lower eyelid drooping (ectropion) or to enhance the appearance of the eye by giving it a more almond-shaped look.
• Medial Canthoplasty: This type of surgery is less common and focuses on the inner corner of the eye near the nose. It is usually performed to correct congenital deformities or trauma in the inner canthus.
• Epicanthoplasty: Sometimes performed in conjunction with medial canthoplasty, epicanthoplasty removes the epicanthal fold—a small skin fold over the inner corner of the eye. It is popular in East Asian countries where patients may seek to open up their eyes and create a more prominent eyelid crease.

Canthoplasty can be performed for both cosmetic and functional purposes. Common indications include:

• Cosmetic Enhancement: Many patients undergo canthoplasty for aesthetic reasons, seeking an almond-shaped or “cat eye” look. This procedure can make the eyes appear larger and more youthful.
• Eyelid Malposition: Conditions such as ectropion (outward turning of the eyelid) or entropion (inward turning of the eyelid) may necessitate canthoplasty to restore normal function.
• Trauma or Injury: Trauma to the eye area, including fractures of the orbital bones or eyelid lacerations, may require reconstructive canthoplasty to restore normal appearance and function.
• Aging: With age, the tissues around the eyes weaken, leading to sagging or drooping lower eyelids. Canthoplasty can restore a more youthful appearance by tightening the tissues around the eyes.

The canthoplasty procedure typically lasts between 1 to 2 hours and is performed under local anesthesia with sedation or, in some cases, general anesthesia. Here’s what to expect during the surgery:

• Incision: A small incision is made at the outer corner of the eye to expose the lateral canthal tendon, which supports the eyelids.
• Tightening: The surgeon tightens and repositions the tendon to elevate the outer corner of the eye and secure the lower eyelid in place.
• Reshaping: The eye is reshaped to achieve the desired look, whether it’s a more youthful appearance or a correction of a functional issue.
• Suturing: The incision is carefully closed with fine sutures, and the new canthal position is secured. The surgeon ensures symmetry between both eyes.
• Bandaging: In some cases, a small bandage may be applied to protect the area and aid healing.

• Aesthetic Enhancement: Canthoplasty offers a dramatic improvement in the eye’s appearance, providing a lifted, almond-shaped look. It can create a more youthful and refreshed appearance.
• Functional Improvement: For patients with sagging or malpositioned eyelids, canthoplasty improves eye function by restoring proper lid positioning, enhancing vision, and protecting the eye from irritation.
• Minimal Scarring: The incisions are typically very small and hidden within the natural crease of the eye, resulting in minimal visible scarring post-recovery.

As with any surgical procedure, canthoplasty comes with potential risks, including:

• Infection: As with any surgery, there is a risk of infection. Proper aftercare and hygiene are essential to prevent complications.
• Scarring: While scarring is usually minimal, in rare cases, excessive scar tissue may form, affecting the appearance of the eye.
• Asymmetry: There is a slight risk that the eyes may not appear perfectly symmetrical after surgery.
• Overcorrection or Undercorrection: An overly tightened or insufficiently tightened lower eyelid can lead to an unnatural appearance.

The recovery process following canthoplasty is generally smooth, but it’s essential to follow the surgeon’s post-operative care instructions for optimal results. Here’s what to expect:

• Swelling and Bruising: Mild to moderate swelling and bruising are common in the first week after surgery. Cold compresses can help reduce these effects.
• Pain Management: Patients may experience minor discomfort, which can usually be managed with over-the-counter pain relievers.
• Sutures Removal: Sutures are typically removed within 5 to 7 days after surgery.
• Return to Normal Activities: Most patients can return to their normal activities within 1 to 2 weeks, though strenuous exercise should be avoided for about 4 weeks.

Canthoplasty is a versatile and transformative procedure, offering both aesthetic and functional benefits for patients. Whether you are looking to rejuvenate your appearance, correct eyelid malpositions, or repair trauma-related damage, canthoplasty can provide dramatic results with minimal scarring and a relatively quick recovery. As with any surgical procedure, consulting a qualified and experienced oculoplastic surgeon is crucial to achieving the best outcomes. If you’re considering canthoplasty, a thorough understanding of the process, risks, and benefits will help you make an informed decision and enjoy the life-changing results of this advanced eye surgery.
